Sur*_*ren -1 python combinations dictionary nested permutation
我的示例字典是:
sample_dict = {
'company': {
'employee': {
'name': [
{'explore': ["noname"],
'valid': ["john","tom"],
'boundary': ["aaaaaaaaaa"],
'negative': ["$"]}],
'age': [
{'explore': [200],
'valid': [20,30],
'boundary': [1,99],
'negative': [-1,100]}],
'others':{
'grade':[
{'explore': ["star"],
'valid': ["A","B"],
'boundary': ["C"],
'negative': ["AB"]}]}
}

它是一个“后续”问题 ->拆分 python 字典以生成所有值组合
我想得到一个隔离的组合列表,如下所示
有效组合:[仅从有效数据列表中生成]
COMPLETE OUTPUT for VALID类别 :
{'company': {'employee': {'age': 20}, 'name': 'john', 'others': {'grade': 'A'}}}
{'company': {'employee': {'age': 20}, 'name': 'john', 'others': {'grade': 'B'}}}
{'company': {'employee': {'age': 20}, 'name': 'tom', 'others': {'grade': 'A'}}}
{'company': {'employee': {'age': 20}, 'name': 'tom', 'others': {'grade': 'B'}}}
{'company': {'employee': {'age': 30}, 'name': 'john', 'others': {'grade': 'A'}}}
{'company': {'employee': {'age': 30}, 'name': 'john', 'others': {'grade': 'B'}}}
{'company': {'employee': {'age': 30}, 'name': 'tom', 'others': {'grade': 'A'}}}
{'company': {'employee': {'age': 30}, 'name': 'tom', 'others': {'grade': 'B'}}}

负组合:[这里有点棘手,因为负组合也应该与“有效”池相结合,至少只有负值]
NEGATIVE 类别的完整输出:
=>[基本上,排除所有值都有效的组合 - 确保组合中至少有一个值来自负组]
{'company': {'employee': {'age': 20}, 'name': 'john', 'others': {'grade': 'AB'}}}
{'company': {'employee': {'age': -1}, 'name': 'tom', 'others': {'grade': 'A'}}}
{'company': {'employee': {'age': 100}, 'name': 'john', 'others': {'grade': 'A'}}}
{'company': {'employee': {'age': 30}, 'name': '$', 'others': {'grade': 'A'}}}
{'company': {'employee': {'age': 30}, 'name': '$', 'others': {'grade': 'AB'}}}
{'company': {'employee': {'age': -1}, 'name': '$', 'others': {'grade': 'AB'}}}
{'company': {'employee': {'age': 100}, 'name': '$', 'others': {'grade': 'AB'}}}

在上面的输出中,在第一行中,通过保持所有有效值来测试等级是否为负值 AB。因此,没有必要生成与年龄相同的 30 岁,因为目的是仅测试负集。我们可以为其余参数提供任何有效数据。
边界组合类似于有效 -> 仅边界池内所有值的组合
探索:类似于负 - 与有效池混合,并且在所有组合中始终至少有一个探索值。

sample_dict2 包含字典列表。这里“员工”整个层次结构是一个列表元素,叶节点“等级”也是一个列表
此外,除了“有效”和“边界”之外,其他数据集可以是空的——[],我们也需要处理它们。
有效组合将类似于
{'company': {'employee_list':[{'employee': {'age': 20}, 'name': 'john', 'others': {'grade': ['A','A']}},{'employee': {'age': 1}, 'name': 'john', 'others': {'grade': ['A','A']}}]}}

generate_invalid_combinations()和generate_explore_combinations()以前一样。细微差别:
它不是在否定评估中从有效数组中获取第一项,而是从有效数组中随机获取一项。
像这样的项目的值'age': [30]作为列表返回,因为它们是如何指定的:
'age': [{'boundary': [1, 99],
'explore': [200],
'negative': [-1, 100],
'valid': [20, 30]}],

如果您想要'age': 30更早的输出示例,请相应地修改定义:
'age': {'boundary': [1, 99],
'explore': [200],
'negative': [-1, 100],
'valid': [20, 30]},

边界属性现在被视为“负”值之一。
仅供参考,这次我不打算生成所有输出:调用generate_combinations(sample_dict2)返回结果如下:
